DreamVanta tools
Small tools for a more observable night.
Use these utilities to turn broad sleep guidance into a plan you can inspect. They work without an account. Diary and checklist entries stay in this browser and are not sent to DreamVanta.
Sleep window planner
Choose a wake time and target duration, then see when to begin winding down and when to aim for lights out.
Seven-night sleep diary
Record timing, perceived quality, and a short note for one week. Save locally or export your own CSV.
Bedroom reset checklist
Review light, sound, temperature, devices, and practical room cues, then keep a short action list.
Designed for reflection, not diagnosis
These tools do not calculate a medical need, diagnose a sleep disorder, or interpret symptoms. Sleep duration varies by age and individual context. Use the outputs as a consistent observation aid and discuss persistent sleep problems with a qualified health professional.
